The air medium to which the compressed air pipeline gas belongs should be marked with light gray. More careful friends can find that one is the petrochemical industry standard and the other is the national standard; One is a separate industry standard, and the other is a national mandatory standard. We can easily confirm that the color of compressed air pipe should be light gray.

The selection of the installation site of compressed air pipeline is most neglected by the staff. Often, after the air compressor is purchased, it will find a position at random and use it immediately after piping. There is no prior planning at all. However, such a hasty result will lead to failure of air compressor, difficulty in maintenance and poor quality of compressed air in the future. Therefore, proper installation site is the prerequisite for correct use of the air compression system.

A clean and dust-free working environment is an indispensable condition for the effective operation of the air compressor. Common factory contaminants, airborne dust and debris can quickly clog the air input filter and oil cooler. A plugged air filter will cause the air compressor to lack air input and reduce efficiency and output.

The compressed air pipeline located in the seriously polluted areas such as quarrying, cement and smelting plants must be equipped with auxiliary filters or automatic purification facilities. The clean area outside the power house can be used to introduce air through pipes or the air compressor room can be specially installed. The diameter of any of the above-mentioned pipes for introducing air should be large enough and the number of bends should be small, so as not to form an excessive input low-pressure area.
